Question 370

What type of amplifier circuit is shown in Figure E7-1?

Schematic of a transistor stage with resistors R1, R2, R3, capacitors C1, C2, C3, an input terminal, and an output terminal.
  1. Common base
  2. Common collector
  3. Common emitterCorrect answer
  4. Emitter follower

Explanation

In Figure E7-1 the signal enters at the base through C1, leaves at the collector through C2, and the emitter is held at signal ground by bypass capacitor C3. The emitter is therefore the element common to input and output, making this a common-emitter amplifier.
